I saw this excellent link in the Industrial Physicist online magazine.

http://www.aip.org/tip/INPHFA/vol-9/iss-6/p22.html

It shows a diagram of a "Schematic design of a sealed-tube neutron
generator with a Penning ion source" and gamma-ray spectrum from
various materials.

Hi Wallace:

It is a very nice technology but the entire set is 20,000 bucks
great for companies but not so easy for individuals. In a few years ebay may end up with this stuff..the deuterium version anyway. If you could just get a tube the normal fusor power source would work.

Happy fusoring!

Or the pdf version on http://www.aip.org/tip/INPHFA/vol-9/iss-6/p22.pdf .

It would not have the spectacular glow inside the beautiful grids of the fusor,
but I think it would be easier if you just want neutrons.

One could produce the high voltage with a Vandegraaff generator, but I am
wondering if one could detect some neutrons using a pyroelectric
accelerator:

The setup would certainly be compact: a LiNbO-crystal on a heating resistor
in deuterium under low pressure, and heavy paraffin or something as the
target. Just detecting those presumably very few neutrons would be a
challenge.

And it only uses 1 to 2 Ci of tritium - anybody got any spare?

Yesterday I read that the experiment had been done:
http://nano.chem.ucla.edu/nature.htm

I knew that the result might be publishable in Nature. I had actually tried to get
a student interested in doing this. Anyway, I am happy that I publicly aired the
idea here.

And it is something off my to-do list.
